The estimation of the manufacturing cost of a part in all phases of the design stage is crucial to concurrent engineering. To better estimate the cost for a product, data must be available from both engineering systems and business systems. This paper presents a cost estimation system being developed to support design time cost estimation using the Federated Intelligent Product EnviRonment (FIP...

In this paper we assess the applicability of case-based reasoning to the difficult problem of early software project cost estimation. We conclude that a comprehensive case representation is not available early in the project and suggest instead that the objective should be risk assessment rather than cost estimation. In reaching this conclusion the existing techniques for cost estimation are di...

Software estimation accuracy is among the greatest challenges for software developers. Software development effort estimation is one of the most major activities in software project management. A number of models have been proposed to make software effort estimations but still no single model can predict the effort accurately. The need for accurate effort estimation in software industry is stil...

Accurate cost estimation in the early stage of project lifecycle is essential for both effective financial planning and cost control of construction projects. Previous efforts by the research team have developed a Web-based Intelligent Cost Estimator (WICE) system. This paper describes a further step of WICE research to develop a special-purpose web agent for various highway construction projec...

Within the cost estimation literature and in practice within organisations a range of cost estimation methods are used to predict costs prior to activities being undertaken. Estimates generated utilising different estimation methods provide different projections of the anticipated cost. The projected differences in cost could have a significant impact on the overall viability of a project or th...

Software has a far ranging nature and sometimes it is difficult to predict the cost. So, it was demanded to develop some useful models that predict the accurate cost, schedule and quality of a software product. There is a great need to accurately predict the cost by selecting the appropriate estimation method. Expert Based Judgment is quite successful. Wideband Delphi estimation comes under thi...

Conceptual cost estimation during the early stage of a construction project plays important role for feasibility analysis and project planning. Traditional approaches rely heavily on experienced engineers, and may cause loss of conceptual estimation knowledge of the firm. This paper proposes a method integrates a previous developed conceptual cost estimation method (PIREM) with the ANFIS neuro-...
